** Chess Rules **
I love when folks say stuff like“there are only a finite number of states a chessboard can occupy, therefore a computer can play chess.”

To the folks who say such things — I wish you to play chess with my 6 year old.

Be not confined by rules! The only things governing chess in this house here are the laws of physics!

…and even then, not all need apply.

作者介绍

陈培新，参与国信证券基础平台研发工作（DevOps、微服务治理、Serverless）

国信证券是一家全国性大型综合类证券公司，在 118 个城市和地区共设有 57 家分公司、185 家营业部，根据中证协发布的数据，近年来国信证券的总资产、净资产、净资本、营业收入、净利润等核心指标排名行业前列。

国信证券从 2020 年 6 月开始接触 TiDB，从技术预研到第一个业务上线大约花了半年时间。第一个上线的业务是金太阳帐单，后面陆续在数据中台、服务观测等系统中应用。从只在东莞主机房的 TiDB 部署到 2021 年 9 月实现 TiDB 多机房的部署，并启动国产海光 x86 服务器的试点工作，国信证券在开源 NewSQL 数据库的探索和应用层面，积累了丰富的实践经验。目前， 国信证券共有 7 个 TiDB 集群，节点数量 109 个，最大表 100 亿，支撑了托管、经纪和自营等业务。
